iffy
Good idea. Perhaps nobody thought of it before you.
My personal guess is that they only make computers do the things that they alone can do like operate the brakes, land the plane etc.
Putting the flaps and wheels down is something that can be trusted to the human pilot so it's cheaper to leave him to do it.
Also automate too many things and questions will start to be asked why we're paying this person such a huge amount of money just to tell the passengers that's Mont Blanc on the left hand side and its x degrees Celsius in Gerona, not that they can hear anyway.
